How to Repair Broken Cracked Tractor 4 clynder bolak Case - How to Fixing Tractor Cracked Bolak Case #FixingTractorCrackedBolakCase #CrackedTractor4clynderbolakCase
I've watched loads of these videos now. All kinds of innovative repair techniques and even making parts from scrap with pretty much nothing. Using some machines that look like they date from when the British were there and these blokes have kept them in fine running order. Just imagine if these guys had the kind of infrastructure and international investment that China has had?
That’s what I like the old British tools. And real mechanics that can actually fix stuff not just bolting on new parts until the problem is solved like they do here now. My van is in the garage atm and they have said because the fuel pump has broke they can’t fix it 🤯 I mean cmon look what theses blokes can do without a work bench 🤣
The mastery of cast iron crack repair is very impressive. I got the hebijebies when they drop roll the block right on the head gasket surface right on the dirt.
With the amount of heat they put into that block, I'd think it would need resurfacing to get it back to flat even if they didn't roll it around like that. Not a mechanic or machinist, though, so I may well be wrong.
Sou metalurgista aposentado e tenho admirado muito este tabalho em bloco de aço nodular cinzento. Gostaria de ver de perto . acompanho os videos de voces e os acho muito esforçados e inteligentes.
Так никто же не сказал КАК ДОЛГО этот мотор проработает после такого варварского "ремонта" 😉 Такой ремонт возможен только если стоимость человеко-часа ниже плинтуса.
Удивительно как много можно сделать в таких кустарных условиях,только бы блок не повело от нагрева.Помню,лет 30 назад отец моего друга тоже отдавал блок цылиндров на ремонт с похожей проблемой и его починили,но это было в условиях завода,все ответственные плоскости и ложе под коленвал были отфезерованы.в те времена купить новый блок было невозможно.сейчас такие блоки просто выкидывают.
В 1989 году после встречи с дубом у 2 л дизеля Тойота Корона двигатель отлетел от КПП , отломав при этом все 4 точки крепежа. Приварил, отцентровал и собрал. Машина после этого прошла не менее 500 т и до сих пор на ходу.
@@user-id9eu5hu2y ,скорее всего так.Причем не всякое гомно подойдёт. ИМХО,он не припоем паяет.Медно-цинковый или серебряный. Очень уж на сварку ацителеном похоже.Вроде в качестве присадки куски гвоздей и проволки
Мне одному кажется что они напоминают Джав из Звёздных воин, которые чинили все подряд, да и ускоренное видео добавляет атмосферы. Ощущение что если оператор снимет панораму, то где нибудь поблизости будет стоять пустынный краулер)).
It's a massey ferguson tractor engine block built in pakistan under licence by MILLAT TRACTORS LAHORE Pakistan. sub stsndard casting, they don't use perkins engines any more, they use copy of perkins engines assembled by millat tractors parts sourced from China and local vendors and small local sub standard parts manufacturers. Engine called millat m4
He didn't weld it, he brazed it (called "silver soldering" in some countries, as it is in fact a form of soldering, but much much stronger, and works on steel and cast iron), which is the right way to repair cracked cast iron, due to the lower temperature required, reducing warpage and further cracking. You saw him dip the braze in flux a couple of times. He probably used a lot more flux, but it got edited out. The whole process may have taken up to 2 hours. But he is highly skilled.
@@keithammleter3824 omg lmao I can braze and tig mig stick weld lmao it’s a general comment inspector gadget! A lot people who don’t know what he is doing will understand weld better. I couldn’t talked about how he un hardened the steel using those wired coals before he started 🤣🤣.. but I didn’t want waste people time reading unnecessary long responses like this one !!!!!!! most people are generally smart stop taking you tube comments to heart.
@Indigenous Onlooker : It's not the slow cooling AFTER welding/brazing that is so important. It is sufficient that it cools slowly enough that no significant temperature gradient develops - it's one part hotter than another that causes the cracking. What is important is to slowly raise the temperature of the whole thing before welding/brazing, so the the local increase in temperature during welding/brazing does not impose stresses that will remain and cause cracking even if the after-cooling is very slow. That is also why it is best to braze old cast iron rather than welding, as the local increase in temperature is kept to a minimum.
I enjoy my evenings watching these videos. Both adult and young men being resourceful in making mechanical repairs. Here in the U.S.A. all you see and hear is rubbish. Forbid anybody actually working or being resourceful. I’m grateful that God has allowed me to productive and useful to others. 👍

As a retired welder all I can say is that guy is a real butcher. The last thing you want to do is to carburize a weld. It becomes brittle. All that dung is loaded with carbon. All I could see was contaminated welds which will eventually crack and a block that is probably so distorted from the uneven heating. All I see is a waste of time and resources. 👎👎👎👎👎
Idk, cast iron already has a lot of carbon, and is already very brittle if not heat treated . I do wonder why they don't heat it and cool it slowly after welding, though? Less brittle?
These videos remind me of Super Glue commercials. It looks good on video and may even pass for a little while. But after so long someone tries to put water in the vase and use it again.
I'm all for fixing rather than throwing away and replacing. But you have to draw a line somewhere, and for me, this was way past it. Acetylene might have been worth more that the block. But a great effort.
@@Shane-zx4ps If we really think about it, we can only surmise that it's a good fix otherwise, no truck driver/operator would gamble on a fix like this if they are not certain that it would last long. The reason being if a fix like this constantly breaks, he will eventually lose his trucking business due to delays in delivering cargo entrusted to him. In turn, these welders will also lose people's confidence in them, eventually, they too would lose their business. For how long it will last is anybody's guess. But I'm pretty sure it will last long as their livelihood and lives depend on it.
@@edwinso8173. Well said, but in saying that, that engine probably gets fixed numerous times by these guys, as it’s cheaper than buying a new engine which they cannot afford..
@@Shane-zx4ps If you mean the very same spot of the same truck part getting welded over and over again then I doubt it very much. The driver/operator would lose his trucking business due to repeated cargo delivery delays or even losing the cargo altogether due to spoilage if it's perishable. But if you mean some other parts getting fixed by other specialists in the area then yes I believe so. You should watch the vid about their mountain roads, you might get a clearer picture of what I'm talking about.
I guess there is more than 1 way how to use cow shit beside using it for cooking . Never a good sign to see your engine block being worked on while laying on the dirt.
Я когда то проходил по теории сварку чугуна автогеном , то есть делаем слега красноватое пламя , чтобы была подача углерода , чугунные прутки и вперед .... Но это в теории так , а у чугуна напрочь отсутствует пластичность , то есть у него только два состояния - жидкое и твердое , чуть перегрел и все вытекло к херам ... Но вот я наконец увидел , как проводится такая процедура сварки в кустарных условиях . Что тут сказать ? - молодцы ! - чугун по чугуну в сечении дает чугун , который легко обрабатывается слесарным инструментом .
Кусок говна за место припоя это просто гениально. Все я теперь перед сваркой все детали буду говном смазывать. PS О великий сенсей благодарю вас за урок гениальной сварки.
Sin herramientas es complicado trabajar pero el Ingenio de cada uno es capaz de al alcanzar la victoria y trabajar para poder comer unos artistas !!! 😶
Damn I'm glad I don't live in Pakistan. I would never get anything done. I'd be hanging around these shops watching what they do "what you doing old man?? .... Learning.
@@derekcollins1972 1of many things.buut 1 would be when smashing something together with a hammer you could use a piece of wood.surely they still have trees around.??
